Killing the char on the end of a char array

This is more of a basic C++ question than anything to do with Mac programming:
I have a dynamic char array (char* charArray = new char[6]). Then I read some text into it with the fscanf() function. Now, I just need to chop off the last character in this array, but it wont let me do: charArray[(last letter)] = '', and it doesn't work by setting it to NULL, either...how do I do this?
This seems like it would be a fairly common question, but, once again, after drudging through the material I found of Google, I didn't find anything useful, so I thought that I would post here

Thanks guys ^_^

Code:

unsigned length = strlen(charArray);

if (length > 0)

{

    charArray[length - 1] = '\0';

}

If you're in C++, though, you should seriously consider using std::string instead of char arrays. It's much easier to use, and much safer, too.
